This experiment was carried out with the help of spectrophotometer using an artificial UV light source to find -out the percentage transmission of UVA and UVB regions of the UV spectrum. The aim of the experiment was to select the transparent medium which would block mum UVB at the same time allowing mammum UVA to pass through thus reducing the unwanted side effects of UVB light and reducing the efficacy of PUVASOL. It was observed that an ordinary plain 3.3 mm colorless glass was the best transparent medium and with its use a simple solarium could be constructed to treat patients on PUVASOL with sunlight as the source of UV light.

A quantitative assay of porphyrins in blood'of thirty patients with atopic dermatitis was done. Rimington's technique for the estimation of porphyrins was employed. Porphyrin levels in thirty cases of atopic dermatitis were compared with levels in ten controls. No satistically significant difference in porphyrin levels was observed be the study and control groups. Porphyrin were also compared between patients with and without history of photosensitivity. The, erythrocyte coproporphyrin in patients with photosensitivity was significantly higher than in patient without Photosensitivity.

A delayed, Tuberculin type response to intradermal (ID) test with benzathine penicillin is described in a 50 year old female. She did not develop any sign of drug reaction on receiving.intramuscular injection of that drug. None of the 65 patients who were studied in detail for the ID test response to various penicillins showed such a delayed response.

Two hundred and eithteen cases of fungal skin infections were studied. Tinea cruris was most common (34.4%), followed by tinea corporis (23.8%) znd tinea pedis (21.6%). Tinea versicolor (8.7%) tinea manum (4.6%) tinea ungaium (3.7%) and tinea capitis (3.2%) were also seen. The male: female ratio was 4:1. The total isolates were 117. Trichophyton rubrum was the most common isolate (35%). closely followed by Epidermophyton floccosum (31.6%). Trichphyton mentagrophytes (17.9%), Malassezia furfur (13.7%) and Microsporum audouini (1.7%) were the only other isolates.

ABO and Rh blood groups among 54 syphilitics were determined. A significantly increased incidence of syphilis in persons blood groups B and AB was observed; significant decrease in those having groups A and 0. A significant decrease in, the incidence of syphilis was also observed in Rh negative 'subjects. These results suggest a possible relationship between the inheritance of blood groups and the natural defence mechanism against syphilis.

A case of Aspergillus sydowi infection of left middle finger nail is described ' The presence of fungal hypae with phialids and spores on direct microscopy as well as in culture, the colour of the sub-ungual mass of the nail resembling the colour of the fungus in, culture' repeated isolations of A sydowi from the diseased tissue along with the absence of any established pathogenic species in the specimen are taken as evidences that this fungus was invading the nail tissue.

This report describes a patient in who repeated episodes of urtican'a were associated with urinary tract infection. Most of the times urticaria subsided following treatment with antibacterial drugs alone.

Three cases of chromomycosis proved histopathologically are reported. In one case Phialophora pedrosoi was grown in culture which was confirmed by the Mycological Reference Laboratory, London. The saprobic form could also be seen in tissues. The significance of this finding is discussed. Hamycin was founduseful in controlling itching.

A rare disease, hypertichosis universalis congenita was seen in a 7-month-old male child. Father also had a similar disorder. There was long black hair all over the body of the child except on the palms, soles and genitalia. Patient has been advised electrolysis when he is about 8 years of age. A brief review of literature in included.
